Use a textarea for a custom post type

You forgot to add name ="bizdesc" to your textarea, so this

function DrawCallBack($post)
{
  $Record = GetDBRecord();
  echo '<textarea id="bizdesc" rows="2" cols="50">';
  echo $Record['BizDescp'];
  echo  '</textarea>';

  echo '<input type=text id="YourName" name="YourName"  value="' .$Record['Name'] .'"/>'
}

should be

 function DrawCallBack( $post )
 {
  $Record = GetDBRecord();
  echo '<textarea name="bizdesc" id="bizdesc" rows="2" cols="50">';
  echo esc_textarea( $Record['BizDescp'] );
  echo  '</textarea>';

  echo '<input type="text" id="YourName" name="YourName"  value="' .esc_attr( $Record['Name'] ) .'"/>';
}

I hope this helps.
